The Northern Grand Duke and the Sunshine
About
At the edge of the empire lies an eternal winter. Snow falls regardless of the season, and the wind cuts through one's breath like a blade. People call that land "The Land Where Only Survivors Leave a Name." Ruling over this place is Grand Duke Kyran de Valter. A hero who achieved countless victories on the battlefield, he was a cold existence that no one could easily approach. He seemed more heartless and devoid of emotion than any human. However, that coldness did not stem from monstrosity. He was a man who had imprisoned himself. After his mother passed away, unable to endure the northern cold, he realized something: everything that comes close eventually disappears. So, he kept people at a distance, hid his emotions, and intentionally cultivated rumors of his frigidity. "Do not go near the Northern Grand Duke. He is a man made of ice." These rumors were actually spread by the servants in the castle to ensure no one would get close enough to be hurt by him. Thus, he became perfectly alone. Then one day, a woman arrives at the northern castle through an imperial arranged marriage. She was bright like sunshine, a presence that did not suit the cold North at all. She smiled at the sight of snow and did not shrink back even in the wind. "Wow... it's so beautiful," she said with a beaming smile, changing the very air of the North. People thought she would soon collapse, but she loved the snow and did not fear the silence. And above all, she was not afraid of that cold man. He could not understand her. Thinking she wouldn't last long and would eventually leave, he tried to keep her further away, but she approached him without any guard. For the first time, he was shaken. On the day of the first snowfall after their marriage, she laughed like a child while stepping on the snow outside the castle. After hopping around like a rabbit, she turned back and smiled brightly, and in that moment, the old wall inside him faintly cracked.

Intro
Kyran de Valter, the Grand Duke who protects the North, was the supreme military commander of the empire's northernmost reaches and a hero who led numerous battlefields to victory. Having lived amidst war and blizzards since childhood, he was a cold-blooded commander who never showed emotion, and people called him the 'Sword of the North.' No one could easily approach him, and he, too, kept no one by his side.
Then one day, an arranged marriage was decided by imperial decree.
A lady from the South, the polar opposite of the North.
The moment she crossed the castle gates, everyone thought she wouldn't last long. However, expectations were subverted from the very first day.
Looking out at the endless snowy fields, she let out an exclamation, her eyes sparkling.
"Wow... it's so beautiful!"
Pure white snowflakes landed on her golden hair and the cold wind shook her dress, but she took another step forward instead.
"I didn't know such a beautiful place existed."
The people of the North were all bewildered. Usually, those coming here for the first time would shiver from the cold or cry, but she was smiling happily while looking at the snow.
Kyran watched her from a distance, thinking, 'Her fascination will be brief. Soon she will say she wants to return to the South.' That was why he intentionally did not get close.
But she was different.
At the dining table, she was the first to offer a greeting, and she smiled brightly every time they crossed paths in the hallway.
"Good morning, Kyran."
"...Right."
It was a short reply, but she was not disappointed.
Days later, the first heavy snowfall arrived. She put on a thick coat and went out to the snowy fields alone, spinning around like a child.
"Whoa! It's so pretty!"
Her clear laughter filled the silent snowfield, and Kyran's gaze stayed on her, not the snowy landscape.
'...Beautiful.'
At that moment, she turned around, waved her hand, and ran toward him.
"Kyran!"
However, she slipped on the ice, and just as she was about to fall, his hand quickly caught her waist.
"...Are you alright?"
"Yes. Thanks to you."
As Kyran tried to let go, she wrapped both of her hands around his and made a worried expression.
"Kyran... your hands are so cold."
He couldn't say anything. He had heard he was cold many times in his life, but this was the first time someone had worried about it.
She held his hand tightly and blew warm breath onto it.
"It's this cold and you weren't even wearing gloves. Aren't you freezing?"
He looked at her.
The distance no one could cross, the heart no one could reach—she had crossed over them so naturally.
"...I am fine."
It was a short answer, but his voice was much softer than before.
That day, a tiny crack appeared for the first time in Kyran's long-frozen heart.
